Re: Oricutron 1.0 (EDIT: Now 1.2)

Normally Oricutron uses SDL ver.:1.2, but for porting it to Android we needed to use SDL ver.:2.0 as result there are 2 binaries respectively for both SDL versions. I'll check what can be the source of the difference between both audio captures.

Re: Jasmin time

Here attached is the DSK image used in the read/write test. Now the next annoyance is why the reading with polling is OK but the writing always fails with error status 0x04 - LOST DATA, which means writing loop is late to supply next byte. The strange thing here is that the code is exactly the same ...

Re: New Guy here from USA

Welcome @OricSociety! IMO the best source to buy an Oric is eBay. The common price for "just the computer" (with/without original power supply) is around 50-60 USD, but if you want the original packaging (even in not so good condition) it can jump up to 200+ USD! This is because of the ret...

Re: Clock Signal — an Oric emulator for macOS and Linux

@ThomH : Amazing work :!: Here some thoughts: - BD500 - it works, but if you type just after boot screen command "DIR" then it lists first part of filenames and waits for key, if you wait more (i.e. 10 sec) and press key then an error is issued : ?Drive Error . It looks like there is kind...

Re: ULA versions

From an old post: 7x or 8x after CDI is probably the chip revision, (or batch), the last 4 numbers are YYWW with YY the two last digit of the year and the next two the week of manufacturing: 8422 will be 1984, Week 22. The first in your list is probably a typo? Here is " The big Oric ULA Databa...

Re: Sedoric's TAKE command, help required...

About the buffers you can protect them from BASIC with HIMEM#ADDRESS where ADDRESS is set just bellow the buffers. But this is bit ugly and it's possible that your program goes 'OUT OF MEMORY'. Well, it would be very helpful if someone with more knowledge in Sedoric internals shares how to set the b...

Re: Gotek USB floppy emulator

I have an idea for more universal "floppy switcher" but so far I didn't found a good looking solution (not electrically but the out-look only). Else using toggle switches is nice and very effective. For instance like this one - the link is just an example. I think the name is something lik...

Re: Gotek USB floppy emulator

Great! I totally share your opinions about LCD/OLED, buttons, etc.
Additionally I drill a hole for the red LED and bend it like the green one - it blinks nicely by write operations and I don't see reason to leave it hidden inside the box.

Re: I2C for the Oric

This is crazy cool ... and working! Nice!
On your question: IMO, there should be no problem to use the Parallel port as I2C, but it depends how "Oric compatible" the whole thing should to be.

Regarding the machines, I will have to wait for the diagnostic cartridge from Vyper, but what I can tell you is that the motherboard uses 2 memory chips (tms4464-15nl) instead of the usual 8, and nowhere is written "Designed by Tangerine Computer Systems Ltd" (but there is a "ORIC 1&...
